Unlock Efficiency in Sticky Food Processing with Karvil Machinery
In the food manufacturing industry, high-viscosity materials pose a unique challenge. From dense protein bars to chewy licorice and bubble gum, achieving a uniform mix without compromising texture or machine durability is critical.
At Karvil Machinery, we don’t just build mixers; we engineer solutions for the toughest mixing challenges. With over 20 years of experience and a footprint in 50+ countries (covering most of Europe and North America), we are proud to introduce our latest innovation designed for the confectionery industry.
We recently completed the manufacturing of two sets of 500L Screw Discharge Kneaders for a valued client in Spain. These machines are specifically engineered to handle Licorice Waste (scraps)—a notoriously difficult material due to its sticky, temperature-sensitive nature.

What makes these machines special?
To ensure the licorice remains pliable and flows tailored for the production line, we engineered a Full Heating System. Unlike standard mixers, these units feature heating jackets on every critical contact surface:
✅ The Main Bowl (Mixing Chamber)
✅ The End Plates
✅ The Screw Barrel
This comprehensive heating design ensures that the material maintains the perfect temperature from the mixing phase right through to extrusion, preventing solidification and ensuring a smooth, continuous discharge.
Our Sigma Mixers (Z-Blade Kneaders) are the industry standard for processing heavy, viscous, and elastoplastic materials. While our recent success is in licorice, our technology is driving efficiency across the food sector:
1. Protein Bars & Energy Bars
Modern health foods require precise mixing of whey, syrups, nuts, and grains. Karvil kneaders ensure a homogeneous blend without crushing delicate ingredients, providing the consistent texture consumers love.
2. Chewing Gum & Bubble Gum Base
Gum production requires high torque to knead the rubber base with sweeteners and flavors. Our heavy-duty design creates the perfect shear force to elasticize the gum base efficiently.
3. Confectionery Rework
Recycling production waste (like our Spanish client’s licorice) requires robust machinery that can melt and re-integrate cured products back into the line, saving costs and reducing waste.

We understand that the Western market demands reliability, safety, and compliance. Here is why Karvil has been a trusted partner for over two decades:
Sanitary Design: All contact parts are crafted from high-grade Stainless Steel (304/316L) with mirror polishing to meet strict FDA and GMP food safety standards.
Customization: From vacuum systems (to remove air bubbles) to screw extrusion discharge (for direct connection to forming lines), we build to your specific requirements.
Durability: Our gearboxes and motors are sourced from top-tier brands, ensuring our machines run 24/7 with minimal downtime.
Global Reach: We successfully export to almost every country in Europe and the Americas, handling all logistics and compliance documentation seamlessly.

Whether you are producing traditional licorice in Spain or high-protein snacks in the USA, Karvil Machinery provides the mixing technology you need to scale.
